Big Lebowski, The - Sunglasses Disappearing
In the scene when the Dude gets his car back, drops the bud then crashes into the dumpster, he is looking for the beetle that is following him. When he turns his head one way, his sunglasses are crooked on his face, in the next shot, when he looks the other way, they are gone.
Video, maybe slo-mo
